    • Asymmetrical bleach activators are provided. The compounds have formula (I), wherein L is a leaving group selected from the group consisting of: (II), (III), (IV), (V) and (VI); wherein j is 0 or 1 and furthermore, when j is 0, then i is 0, and when j is 1, then i is 0 or 1. The spacer group Z, when present, is selected from the group consisting of C2-C16 linear or branched, substituted or unsubstituted alkyl, alkaryl, aralkyl, aryl, and (VII), wherein m = 1 to 10 and each of R -R are independently selected from H and CH3; wherein the group G can be R or R ; R is a C7-C13 linear or branched chain saturated or unsaturated alkyl group, preferably a C7-C11 linear or branched chain saturated alkyl group, R is independently selected from the group consisting of C1-C8 linear or branched chain saturated or unsaturated alkyl, alkaryl, aralkyl and aryl, preferably a C1-C4 linear saturated alkyl group and R is a C1-C4 linear or branched chain saturated or unsaturated alkyl group. Preferred compounds include the compounds when R is a C7-C11 linear or branched saturated alkyl group, and most preferably when R is a linear C8 or C9 saturated alkyl group and R , when present, and R are CH3. Bleach additive and bleaching compositions including the asymmetrical bleach activators and methods of cleaning fabrics are also provided. 00000
